LAN9353TI/PT

Controllers Overview

The LAN9353TI/PT is a 3-port managed Ethernet switch featuring integrated 10/100 Base-T/TX PHYs with HP Auto-MDIX. It supports up to 200Mbps via Turbo MII and includes an IEEE 1588v2 hardware timestamp unit for precision timing. The device operates on a single 3.3V supply using an integrated 1.2V regulator, with I/O voltage ranging from 1.8V to 3.3V. It provides 32K buffer RAM, a 512-entry forwarding table, and comprehensive QoS features including VLAN support and rate limiting. The component is housed in a 64-pin TQFP-EP package.

Controllers Feature Summary

• Integrated 10/100 Ethernet PHYs with high-performance switching fabric
• IEEE 1588v2 hardware timestamping for boundary and transparent clock modes
• Advanced Quality of Service (QoS) with dynamic queues and VLAN tagging
• Flexible management interfaces supporting I2C and SMI protocols

Controllers Applications

• Cable, satellite, and IP set-top boxes
• Digital televisions and video recorders
• VoIP systems and home gateways
• Test and measurement equipment

Controllers Procurement Notes

Verify the specific suffix 'TI/PT' against the manufacturer's current datasheet to confirm the package type and temperature range. Ensure compatibility with system power requirements, specifically the single 3.3V supply configuration. Confirm that the host interface matches the supported MII/RMII/Turbo MII modes. Check for any recent product change notifications regarding assembly sites or material composition updates.

Controllers Selection Notes

Select this component when a managed switch solution with integrated PHYs is required for embedded applications. It is suitable for designs needing precise time synchronization via IEEE 1588v2. Consider the 64-pin TQFP-EP package constraints for PCB layout. Evaluate the need for external EEPROM if static configuration storage is desired, as the device includes an internal controller for this purpose.

Controllers Part Context

This part belongs to the LAN935x family of 3-port managed Ethernet switches from Microchip Technology. It shares architectural similarities with the LAN9352 and LAN9354 but offers specific port configurations and interface options. The TI/PT designation indicates the commercial temperature range and the 64-pin TQFP-EP packaging format.

Controllers Replacement Considerations

Publicly confirmed substitutes include other members of the LAN935x family, such as the LAN9352 or LAN9354, provided pinout and feature requirements align. Verify register compatibility and firmware support before substitution.
